# EvaluationBedrockModel


Contains the ARN of the Amazon Bedrock model or [inference profile](https://docs.aws.amazon.com/bedrock/latest/userguide/cross-region-inference.html) specified in your evaluation job. Each Amazon Bedrock model supports different `inferenceParams`. To learn more about supported inference parameters for Amazon Bedrock models, see [Inference parameters for foundation models](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters.html).

The `inferenceParams` are specified using JSON. To successfully insert JSON as string make sure that all quotations are properly escaped. For example, `"temperature":"0.25"` key value pair would need to be formatted as `\"temperature\":\"0.25\"` to successfully accepted in the request.

 ** inferenceParams **   <a name="bedrock-Type-EvaluationBedrockModel-inferenceParams"></a>
Each Amazon Bedrock support different inference parameters that change how the model behaves during inference.  
For code examples that demonstrate how to use the `inferenceParams` parameter, see [Create a model evaluation job in Amazon Bedrock](https://docs.aws.amazon.com/bedrock/latest/userguide/model-evaluation-jobs-management-create.html#model-evaluation-jobs-management-create-auto).

 ** performanceConfig **   <a name="bedrock-Type-EvaluationBedrockModel-performanceConfig"></a>
Specifies performance settings for the model or inference profile.  
Type: [PerformanceConfiguration](API_PerformanceConfiguration.md) object  
Required: No
